swrrCn-TiinowiNG DEviCE'.

v.To all whom t may concern:

minion of Canada,`have invented certainV new andV useful Improvements in Switch- Throwing Devices, of which the following is a specification.

' This invention relates to` improvements in means for actuating switch points as used in connection with the V running rails of steam and` street railroads. 4 The principal object of the-'invention is to provide a'device arranged alongside of the track which may be operated by a passing car or locomotive by pressing a lever in advance ofthe switch so that the same will be moved prior to the-entry of the car there- A 'further object is Vto provide vmeans whereby the switch points are held firmly in eitherofj their adjusted positions.

Another object is `to provide means which are positiveV in their' operation and comprised of 'fewV and simple arts,

Thesefand other like objectsare attained rlhe oppositeJ end of the link bar 40-is enby the novel construction andcombinati'onV of parts hereinafter described, and shown in the accompanying drawings, forming'a materialv part of this disclosure, and in which- Y Y Figure 1 is a fragmentary plan `iview, showing a section of a trackV including a curve and indicating the application of the invention. 'o v Fig. 2'V is a fragmentary side elevational view, partially diagrammatic and indicating the application of the operating means to view similar to Fig. 1.

Fig. 4 is a transverse sectional view, taken on line 4-'4 of Fig. 3. o

Fig. 5 is a similar transverse view, taken on line 5-5 of Fig. 3.

Fig. 6 .is another; transverse sectional view, taken on line 6-6 of Fig. 3, and

Fig. 7 is another plan view, similar to Fig. 1 but showing a modification.

In the drawings, the numeralV 10 indicates a through rail 11 the mating rail, `the latter being bent outwardly at 12, the straight rail13 having pivoted to its end a tongue 14, while with the concentric rail 15 is similarly connected Vthe switch tongue 16, all o'f the several rails resting upon ties or sleep- Fig. 3 is an enlarged' fragmentary plan Specification of LettersPatent,

sectional ers 17, 'constituting a conventional type ofA railroad construction.

In Fig. 2 a car is indicated by broken lines 20, upon which is mounted a rigid "bracket 21, having an operating lever 22 fulfixed bracket 29, the other arm 30 of the lever connecting with the link 32,

engaged with a plunger 33, slidably mounted in a bracket 34, attached l transversely to the lower side of the car floor and adapted to Vbe extended out by actuating the lever 22.

A plate lever 36 is pivotally securedto the rail 10`by bolt 37, and has fixed in it a post .38 with which the plunger 33 is adapted to make contact when in an extended position so as to cause the plate to pivot uponthe bolt 37, moving it forward and Vactuating a Ilink bar 40, pivoted to the plate Y36 bya pin 41.

outer corner substantially in register with the slot 48 is another pin 52 operating within a slot 54, formed in a head 55 of a bar 56 to which is attached the end of a switch-bar 56 adjacent to the head, the other extremity of the bar being connected with a bracket 58, engaged with the switch point 14. Thus the bai` 56 acts as a distance rod between the switch point and through which they are moved by the mechanism described.

From the foregoing it will be Seen that when the plunger 33 is moved outwardly, it will engage with the upstanding post 38 and through its connections, cause the triangular plate'45 to rotate so that the end 49 of the spring element will move within the slot 48 into the position shown in broken lines in Fig. 3, thereby locking the switch points in either of their adjusted positions.

The modification illustrated in Fig. 7 shows a pair of fixed points 14 and 16 respectively, engaged by a pair of connecting Patented Oct. 28, 1919. Application fiiediviay i4, 191e. serialA N. 297,114. Y A` `devices may be used to move the switch point after the train has passed, leaving the switch in condition for the neXt succeeding train.

I claim:

1.7111 a switch device, the combination with a pair of running rails and a pair of switch points cooperative therewith, of a plate pivoted remotely from said switch point, an arm formed with said plate adapted to be operatedby the car passing over said rails, a triangular plate pivoted to one of said rails adjacent to said switch point, connections between said plates, a connecting bar extending between said switch points, and means formed with said triangular plate whereby said connecting bar is op erated upon movement being communicated to the iirst named plate.

2, In a switchV throwing device, the combination with a pair of running rails and a Copies of this patent may be obtained for pair of switch points operatively combined therewith, of a plate pivoted to one of said running rails, an arm `formedon said plate, means for actuating said arm, a triangular plate pivoted to the same rail adjacent to said switch points, connections between said plates whereby when said armis Amoved said triangular plateis caused to turn upon its pivot, an elongated slot formed in said trianglar plate adjacent to the longer side thereof, a rigid casing secured alongside of sairdvraih a spring in said casing, an arm extending' from said spring intosaid slot whereby said plate is heldin either adjusted position, and means engaged with triangular piate adapted to operate both ofsaid switch points.

3. In a switch operating device, the combination with a pair of runningrails, `and a paireswitch points operatively combined therewith, of a tricngular plate below one of Said running rails, an elongated slot formedin said triangularplate adjacent to the longer edge thereof, a bar connecting between said switch points, a casing ixed adjacent to said running rail, and a spring element in said casing having anarm eX- tending outward into slot in said triangular plate whereby it may beA heldin. either of adjustedpositions.A

Inv testimony whereof I'have affixed my signature. 4 ,j
